Hello. Ive tried putting gas in the new blazer and everytime the gas nozel turns on for two seconds and gets shut off. I read that maybe I have a vent hose thats blocked? I cant really tell what hoes is what. Can any tell me if this could be my problem and how to fix it?
Please and thanks.

 

What year Blazer? 2 door or 4 door?
EDIT: The anti siphon ball in the filler neck is probably stuck. Whack the lower end of the steel filler neck, right where it connects to the rubber line. There's a plastic ball in there, about the size of a ping pong ball.

 

try what the captain said, hes pretty good around these parts as you will find out as you contribute to the forum.
you can stick your head up under the blazer and take a look to see if anything is pinched or has a hard bend it in. the vent hose is going to be the smaller of the two that go up to the filler part on the outside of the car. if you suspect it being clogged, i would recommend removing it and then blowing some air through it from an air compressor. DO NOT use water.
if you look under there and something is kinked, your gas tank might be out of place. possibly from a fuel pump replacement. check all that out and let us know.

 

Thanks. Ill try tapping on it with something. This is something ive never had any isdue with before. Ill check that hoes while im at it. Really appreciate the help. Thank you both.

Oh. 04 2door xtreme.
